We have a Triton T80SI and for a few weeks now the water has not been
heating up unless the temp dial is turned right up but this slows the water
down rendering it pretty useless. I have changed the can assembly for a new
one but the fault is still there. Could the fault be with the Thermal Cut
Out located on the top of the heater?
Any help would be appreciated
If it's anything like the old Triton shower that I once had there is a group
of microswitches actuated by cams on the controller dial spindle, these
switches controlling the power supply to the individual elements within the
heater boiler. These microswitches used to pack up on regular basis on my
unit, meaning that there were only some of the elements within the boiler
becoming energised, hence the failure to heat the water properly.
You can test by isolating the shower and removing the cover, then operating
the switches by hand. If they give a clear click when they operate that's
usually fairly significant that they're OK. If they all give a clear click,
then it's multi-tester time to eliminate them as a possibility.
If it is the switches I obtained mine direct from the manufacturer at a far
cheaper rate than from Triton.
Is it like the Triton I had, which had two elements controlled by mechanical
One of the relays burnt out, gaving the symptoms you describe.
Looking inside showed the blackened area clearly !
The solder around the pads had melted, so it must have been getting hot.
The relays were marked 10Amp, but were carrying more like 20.
Little chance of safe repair, so new unit bought.
My replacement is a lower power version, hoping it will last longer.
